The elusive chase for the first RR Lyr star in a binary system: the case of KIC 2831097
Ennio Poretti, Jean-Francois Le Borgne, Mercedes Correa +9
The lack of RR Lyr stars in binary systems is an atypical fact when we compared it to other classes of variables. Therefore, it has become a challenge for observers to detect an RR…
Current status of the Extension of the FRIPON network in Chile
Felipe Gutiérrez Rojas, Sébastien Bouquillon, Rene A. Mendez +17
FRIPON is an efficient ground-based network for the detection and characterization of fireballs, which was initiated in France in 2016 with over one hundred cameras and which has b…
Observations of the RRc variable LINEAR 1169665 with the robotic telescope TAROT
J. F. Le Borgne, A. Klotz
LINEAR 1169665 is a RR Lyrae of sub-type c discovered by the asteroid survey LINEAR. The robotic telescope TAROT at Calern Observatory has observed it between the years 2006 and 20…
The historical vanishing of the Blazhko effect of RR Lyr from GEOS and Kepler surveys
J. F. Le Borgne, E. Poretti, A. Klotz +20
RR Lyr is one of the most studied variable stars. Its light curve has been regularly monitored since the discovery of the periodic variability in 1899. Analysis of all observed max…
The all-sky GEOS RR Lyr survey with the TAROT telescopes. Analysis of the Blazhko effect
J. -F. Le Borgne, A. Klotz, E. Poretti +9
We used the GEOS database to study the Blazhko effect of galactic RRab stars. The database is continuously enriched by maxima supplied by amateur astronomers and by a dedicated sur…
Stellar evolution in real time: Period variations in galactic RR Lyr stars
E. Poretti, J. F. Le Borgne, J. Vandenbroere +6
The times of maximum brightness collected in the GEOS RR Lyr database allowed us to trace the period variations of a sample of 123 galactic RRab variables. These data span a time b…
